Miami
No Doubt. No Doubt. No Doubt. Anyone who says otherwisee was not born before 1967.
I was born in 1965; the Dolphins stole my childhood. I hate everyone and everything associated with the Dolphins--their city, their fans, humidity, etc. I eat as much tuna as possible and wish they made gill-netting legal again.
I root against "what's-his-name" when I find myself watching celebrity golf.
My favorite football highlight was Garo Yepremian's botched field goal, pass attempt, and tackle against the Washington Redskins. (Ya want proof that it's my favorite highlight? Mike Bass is the Redskins player.)
I despise how the 1972 team gathers to root against the final unbeaten team each season. Absolutely, positively, no class.
That's just a partial list of the 1970's reasons to hate them; I have twenty five more years of hatred, but I'll spare everyone the details.
I will take a 2-14 season with two wins over the Dolphins over a 7-9 season with two losses to the Dolphins.
I hate Dallas more, though.
